Abstract: A method of creating an optical structure within a photosensitive light transmissive material comprising the steps of: (a) exposing a selected region of the material to radiation at a wavelength selected to effect a refractive index change in the material; (b) terminating the exposure to the radiation at a selected fluence; and afterwards (c) exposing at least one portion of the selected region to UV radiation at a level sufficient to vary the refractive index of the material within the selected region to form the optical structure; wherein the fluence is selected such that the optical structure is substantially thermally stable without a requirement for post-processing annealing.

Abstract: A method of modifying birefringence properties of a waveguide formed within a carrier, the method comprising the steps of inducing a stress anisotropy in the waveguide and effecting a differential decrease in a first refractive index of one mode in the waveguide with respect to a second refractive index of another mode of the waveguide.
